@title{(Grainin nc tr dur in pan envbuf)}


Granulate an input signal

nc - the number of channels to output. If 1, mono is
     returned and pan is ignored.

tr - a kr or ar trigger to start a new grain. If ar, grains
     after the start of the synth are sample accurate.

The following args are polled at grain creation time

dur - size of the grain.

in - the input to granulate

pan - a value from -1 to 1. Determines where to pan the output in
      the same manner as pan-az.

envbuf - the buffer number containing a singal to use for the
         grain envelope. -1 uses a built-in Hanning envelope.
